First, the phenomenon of floor cracking and hollowing.
Over time, the garage floor and factory concrete are prone to cracking and hollowing, which not only affects the aesthetics of the ground, but also affects the performance of the floor. Cracks and hollowing can cause uneven floors, noise and vibration for vehicles and people to pass, and increase maintenance costs on the ground. Therefore, the cracking and hollowing of the concrete of the garage floor and the factory building need to be repaired in time.
Second, the repair plan.
For the cracking and hollowing of the concrete of the garage floor and the plant, the following repair solutions can be adopted:
1.Clean up the base layer.
The first step is to clean the base surface of cracks and hollows, including dust, oil and other impurities. For cracks, a cutter can be used to enlarge the crack to facilitate the penetration of the repair material. For hollow drums, a tool such as a hammer can be used to shovel the surface until a solid base layer is exposed.
2.Preparation of repair materials.
Depending on the severity of the cracking and hollowing, the appropriate repair material is selected. Commonly used repair materials include epoxy resin, polyurethane, cement mortar, etc. When preparing the materials, it is necessary to pay attention to the mix ratio of the materials and stir evenly.
3.Apply the repair material.
The stirred repair material is evenly applied to the surface of the cracked or hollow base layer, and for smaller cracks or hollows, the repair material can be applied directly. For larger cracks or hollows, cement mortar can be used to fill in before applying the repair material.
4.Maintenance.
After the repair is completed, maintenance work needs to be carried out to facilitate the curing of the repair material. Moisturizing methods are generally used, such as covering the patched area with a film or cloth to keep it moist. The curing time depends on the type of repair material and climatic conditions, and is generally not less than 7 days.
5.Acceptance.
After the curing is completed, the repaired area needs to be inspected. The acceptance content includes the appearance, flatness, strength, etc. of the repaired area. If the repair effect meets the requirements, it can be put into use.
3. Precautions for construction.
In the process of cracking and hollowing drum repair of garage floor and plant concrete, the following matters need to be paid attention to:
1.During the construction process, it is necessary to ensure the safety and hygiene of the construction site, and comply with relevant regulations and operating procedures.
2.For larger cracks or hollow drums, reinforcement treatment is required first to avoid safety accidents in the repair process.
3.When applying the repair material, it is necessary to ensure the uniformity and fullness of the material, so as not to affect the repair effect.
4.During the curing process, it is necessary to maintain the humidity and temperature of the repair area so as not to affect the curing effect of the repair material.
5.During the acceptance process, a comprehensive inspection of the repair area is required to ensure that the repair effect meets the requirements.
Fourth, summary. Cracking and hollowing of garage floors and concrete in factories is one of the common ground problems, which need to be repaired with effective repair solutions in a timely manner. In the repair process, it is necessary to pay attention to the problems of construction safety, construction quality and management to ensure that the repair effect meets the requirements. At the same time, it is also necessary to strengthen daily maintenance and management, and carry out regular inspection and repair work to avoid new cracking and hollowing problems.
